Abstract
Temperature dependent electron mobility data from nonpolar CaZrO3/SrTiO3 heterostructures were analyzed and modeled considering various electron scattering mechanisms. We found that the total mobility based on Matthiessen's rule provided good quantitative agreement with experimental data over a wide temperature range (T = 2-295 K). Low-temperature mobility was limited by background impurities and interface roughness scatterings. A crossover between background impurity scattering and interfacial roughness scattering was observed with increasing carrier density. At temperatures of 10 < T < 150, electron-electron scattering was the main scattering mechanism, while at room temperature, electron-electron and polaron-LO phonon scatterings were dominant. © 2018 IOP Publishing Ltd.
